Description
The Trane RLY02138 Control Relay 1NO/1NC 5060Hz is an electromechanical switching component used to manage low-voltage control circuits. It operates by opening and closing normally open and normally closed contacts to enable or interrupt signals between thermostats, controllers and equipment such as compressors or fans in HVAC system connections. It operates as an interface within the control circuit allowing coordinated operation of systems in residential, commercial, and light industrial conditions where reliable switching of 24V control signals is required. It is mounted in control panels for system automation.
